I did searches on other topics but none were relevant to what has happened to me so I started a new thread but does anyone know how to fix the USB Device Not Recognized error on Windows. It happened with my BlackBerry a while ago and the USB port on the BlackBerry was never able to recognize anything ever again like the charger and stuff. My 500GB External Hard Drive which is about 3/4 full of music and other stuff keeps giving me the USB Device Not Recognized error everytime I plug it in. I've tried every USB port on six different computers including laptops both on Windows and Mac and still have no luck. Is there any other way to get something to recognize it and get all the files/folders off of it. I'm almost 95% sure no files have been deleted or damaged on it. Any help would be appreciated.
